just a manipulation of the cones on your fovea... They get bleached a certain contrasted colour, then are immediately exposed to just white gray and black so they overshoot as they remove their bleaching. It just so happens they were witnessing the opposite colours to the colours of the picture so the overshoot showed you the true colour of the picture.

fun trick. Stare at something blue intensely for like half a minute then stare at a sheet of paper, you should see yellow

You learned how negative colours, when shown and then taken away, cause us to see the actual colours.
